A structure or assembly is hyperstatic when you can support one constrain on a node without losing the overall balance.

The thinness of the frame is here to illustrate the optimization work that has been done to get this level of rigidity within the structure.

This results in a very light weight chair, quite transparent with a captivating geometry.

The brass nodes are 3D printed, hyperstat has been designed as a system and will be D.V.EP under various forms: lamps, tables, folding screens, etc…

Brass

One can notice the two different diameters of tubes used in the structure, the larger ones are in compression whereas the thinnest ones in tension. This wiser use of matter further enhances the structural optimization and makes visible.
